MLPerf® Training Reference Implementations

July 14, 2026 · View on GitHub

This is a repository of reference implementations for the MLPerf® training benchmarks. These implementations are valid as starting points for benchmark implementations but are not fully optimized and are not intended to be used for "real" performance measurements of software frameworks or hardware.

Please see the MLPerf Training Benchmark paper for a detailed description of the motivation and guiding principles behind the benchmark suite. If you use any part of this benchmark (e.g., reference implementations, submissions, etc.) in academic work, please cite the following:

These reference implementations are still very much "alpha" or "beta" quality. They could be improved in many ways. Please file issues or pull requests to help us improve quality.

We provide reference implementations for benchmarks in the MLPerf suite, as well as several benchmarks under development.

Each reference implementation provides the following:

Code that implements the model in at least one framework.
A Dockerfile which can be used to run the benchmark in a container.
Instructions to download the appropriate dataset.
A script which runs and times training the model.
Documentation on the dataset, model, and machine setup.

Running Benchmarks

Follow instructions on the Readme of each benchmark. Generally, a benchmark can be run with the following steps:

Setup docker & dependencies. There is a shared script (install_cuda_docker.sh) to do this. Some benchmarks will have additional setup, mentioned in their READMEs.
Download the dataset from mlcommons-storage. This should be run outside of docker, on your host machine. This should be run from the directory it is in (it may make assumptions about CWD).
Optionally, run verify_dataset.sh to ensure the was successfully downloaded.
Build and run the docker image, the command to do this is included with each Benchmark.

Each benchmark will run until the target quality is reached and then stop, printing timing results.

Some these benchmarks are rather slow or take a long time to run on the reference hardware. We expect to see significant performance improvements with more hardware and optimized implementations.
